摘　　要：大数据电商时代,数据交易可使彼此孤立的数据资源得到协同共享与价值利用,营销标签作为电商业务中数据交易的主要形式,拥有巨大的潜在价值.然而传统数据交易市场面临3个主要问题:1)中心化平台信息不透明导致信任危机和恶意竞价排名;2)缺乏合理的激励机制来打破数据孤岛导致数据不流通和共享困难;3)数据安全威胁导致隐私泄露和数据倒卖盗卖等问题.为解决这些问题,设计了一种面向电商联盟的区块链营销标签交易机制DSTS(decentralized data security transaction system),以去中心化为基础设计上层共识激励机制,结合可信执行环境完成系统各项数据交易和计算业务,从而实现了一个安全完备的数据交易生态.通过真实性验证机制确保营销标签有效性,设计共识激励机制使用户积极共享数据,利用智能合约对角色行为按照系统设计规范进行有效约束;随后通过SGX(software guard extensions)远程认证实现密钥传输和数据安全存储,实现了智能合约安全调用来保障用户隐私和数据安全;最后,通过可信计算机制和系统设计思想,实现了数据交易结果的可靠交付.为验证系统的安全性和实用性,采用某电商公司提供的35万条真实数据进行性能测试,测试结果表明系统能够同时保证安全和性能需求,其额外开销主要来自远程认证模块且在可接受范围内.In the era of big data e-commerce,data trading can enable collaborative sharing and value utilization of isolated data resources.As the main form of data trading in e-commerce business,marketing tags have enormous potential value.However,the traditional data trading market faces three main problems:1)The opaque information of the centralized platform leads to trust crisis and malicious bidding ranking;2)Lack of reasonable incentive mechanism to break the data island leads to data non-circulation and sharing difficulties;3)Data security threats lead to privacy disclosure and data reselling and theft.In order to solve these problems,a blockchain marketing label trading mechanism for e-commerce alliance is designed,and the upper consensus incentive mechanism is designed based on decentralization,and all data transactions and computing businesses of the system are completed in combination with the trusted execution environment,thus realizing a safe and complete data transaction ecosystem.The authenticity verification mechanism is designed to ensure the effectiveness of marketing labels,the consensus incentive mechanism is designed to enable users to actively share data,and the smart contract is used to effectively constrain the role behavior according to the system design specification;Then key transmission and data security storage are realized through SGX remote authentication,and smart contract security call is realized to ensure user privacy and data security;Finally,the reliable delivery of data transaction results is realized through the trusted computer system and system design idea.In order to verify the security and practicability of the system,350000 pieces of real data provided by an e-commerce company are used for performance testing.The test results show that the system can guarantee the security and performance requirements at the same time,and its additional costs mainly come from the remote authentication module and are within the acceptable range.
